You shouldn't compare the number of nodes you need to reach a certain depth to the numbers you see in Crafty (or any other engine). Such comparisions simply do not make any sense at all. Crafty and Trueno probably search entirely different trees. They have different extensions, different pruning rules, different quiescence searches, and perhaps even different ways of counting nodes. It is a very good idea to try to reduce the size of your tree (I think you will find that it is the most effective way to improve your engine rapidly), but you should compare the results to older versions of your own engine rather than to Crafty.
